HAY ELEVATOR AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 257,161, dated May 2, 1882.

Application filed October 3, 18S1. (No model.) i

To all whom it may concern:

Beit known that I, EDWIN HARRINGTON, ot' Manchester,in the county of Ontario and State of New York, have invented certain Improve ments in Hay Elevators and Carriers, of which the followingis a specification.

My invention relates to hay elevators and carriers; and the' improvements consist in a vertically-sliding brake and rope-clamping device controlled through the carrying-arms by the weight ot' the load; in stops for holding the apparatus in position on the track, and in other features and details hereinafter more fully explained.

In the accompanying drawings, Fignrel represents a side elevation of my improved apparatus; Fig. 2, a similar view with the side of the shell or casing removed; Fig. 3, a top plan view of the carriage and track, one side being broken away 5 and Fig. 4, a face or edge view of the brake and the rope-pulley.

A represents the shell or casing ot' the carriage, consisting of two side plates, a and b, supported and carried by armsor'levers B, pivoted between said plates,and furnished at their upper and outer ends with supporting and carrying wheels c, which travel upon beams or rails C, as shown.

D represents a vertically-moving brake and rope-clampin g device, formed with ribs d on its sides, which move in recesses or grooves e in the side plates, a b, and serve to guide the brake in its movements. The brake consists ot' an upright stem, the lower end of which is extended laterally and serrated to more effect ually hold the rope E, while the side ribs, d, are carried below the serrated .portiontol engage with lugs f on the sides of the rope wheel or pulley F. rlhe stem or body of the brake is slotted or formed with an opening, g, through From the above it will be seen that unless elevated and held up by special means the brake and clamp will descend andloek the wheel or pulley against rotation and the rope against slipping.

For the purpose of releasing and withdrawing the brake and clamp when at the point for loading or unloading thc brake-stem is furnished with laterally-projecting pins orlu gs h,Y which extend through slotsz' in the side plates of shell or casing and ride upon an inclined block or plate, G, secured to the inner face of the supporting beams or track C, one on each side of the carriage. These blocks or plates are located at any desired pointer points, and, besides having theinclined ends j, are furnished at the top and midway between their ends with a lug or projectionJr, which servesas a stop to limitl the movement of the carriage. v

l l I represent locking dogs or pawls pivoted within the shell or casing A, with their free ends toward each other. rlhe inner or free ends ofthe pawls are formed with laterally-projecting ears Z, which extend through openings m beyond the side plates, c b, as shownin Fig. The

ears lare beveled on their under faces at the out' er sides to ride over the lug or projection k, but have square or upright inner faces to abut against said lug or projection. It will be seen that under this construction the carriage will be permitted to move readily until the ear Z of one of the pawls'rides over andl drops in front of the projection 7c, when the upright face of the ear ofthe opposite pawl will strike the lug or projection and prevent further movement l in that direction, and the tirst pawl will prevent a backwardmovement. The carriage is thus held firmly in place at the desired point, the lug and plate G being, as above stated, placed at the point ot loading or unloading. The lug or projection lc being at the middle of the plate or block G, the carriage is locked at the same time that the brake and clamp are withdrawn. Hence the'gload maygbe raised or lowered, as desired, while the carriage remains stationary. Each pawl I is connected bya link, a, with a depending trip or yoke, J, through the ring o of each of which the hoistingrope E passes, as indicated in Figs. l and 2. Each link is guided by lugs or projections on its sides pass- IOO ing through or into slots in the side plates, a and b. The yoke or trip through which the rope passes down to the load hangs downward in a substantially vertical position, as shown, and as the grappling device is drawn up it comes into contact with the .ring or yoke of the trip and causes the same to rise and elevate the pawl or dog I, with which it is connected, thereby allowing the carriage to ride from the block or plate G and permitting the brake and clamp to be thrown into action.

It will be observed that under the above construction the apparatus is capable ot' being moved and used Without change in either direction at will.

In practice the plates ct and I) may be formed with openings or recesses to receive journals formed directly upon the arms or levers B and dogs I, the plates being tied together by shouldered bolts P or by bolts provided with encircling sleeves or collars to separate and hold the plates apart; or bolts may be employed as the pivots of said parts.

The apparatus constructed as above set forth is simple, cheap, strong, and efticient. Y

I amy aware that hay-elevators have hitherto been constructed or proposed in which the carrying-arms Were pivoted to each other and one ot' the arms provided with a brake and ropeelamp to act upon tliewhcel and rope carried by the other arm. I am not, however, aware that anyone has hitherto provided a hay elevator and carrier with a vertically-sliding brake adapted to act in the same manner, Whether the carrier be moved in one or the other direction without changing its position in relation to the track-that is to say, without turning it end for endand without requiring the Withdrawal of the rope and adjustment of the brake or of the rope-clamp. By my improved construction I am enabled to Work in either direction Without alteration er adjustment 0f any kind.

Having thus described my invention, What I claim is- 1. The herein-described hay elevator and carrier, consisting of shell A, pivoted arms B, pnlley F, brake D, dogs I, and trips or yokes J, combined and operating as set forth.

2. In a hay elevator and carrier, the combination of the body A, pulley F, arms B, and vertically-sliding brake D, controlled by said arms, substantially as set forth.

3. In a hay elevator and carrier, the combination ot'a pulley,averticall y-slidin g brake, and pivoted sustaining-arms extending through the body ot the brake and serving` to apply the Weight ot' the carriage and load thereto, substantially in the manner explained.

4. In combination with the grooved plates ct and b and pulley F, the brake D, having ribs to tit the grooves of the plates, as and for the purpose set forth.

5. In combination with the rope-pulley having lugsfon its sides, the combined brake and clamp D, arranged to slide vertically in the shell or casing, substantially as shown.

6. The vertically-slidin g brake and clamp D, provided with laterally-projecting lugs or pins to engage with a fixed incline, as described.
